Application January 11, 1954, Serial No. 403,156

3 Claims. (CI. 7295) This invention relates to certain new and usefulimprovements in constructional means for supporting chimneys and thelike, particularly in buildings such as dwellings in which a fullchimney extending to ground level is unnecessary, but a superposedchimney section adjacent the roof or an upper level of the building isdesirable, both for utilitarian and ornamental purposes.

Many municipla building codes require the inclusion of chimney-likestructures, particularly for the reception of the discharge ends of ventpipes from household devices such as plumbing, space heating means, andother instrumentalities. It has heretofore been necessary in order toprovide such a chimney-like structure to erect the chimney full size andfull dimension from the lower level of the building, resulting in arelatively expensive structure and one which occupies a substantialportion of the room space in which the unit is mounted. While such fullchimneys are at times desirable in those buildings in which there isample space and in which the lower level portion of the chimneys isdesired for the useful purpose of accommodating a fireplace or otheropening, in many smaller constructions space for such purposes is notavailable and it is substantially imperative that the chimney-likesuperstructure be provided without interrupting the wall space of thelower level room areas.

A principal object of the present invention is to provide supportingmeans adapted to receive and support a chimney-like superstructure,which supporting means are adapted for mounting in the confines of aninterior wall as of a building without interrupting the wall space.

A further object of the invention is to provide such support means whichmay be mounted in and engaged to elements of the wall constructionduring the construction thereof, and which will be concealed in the wallupon the finishing thereof.

Y A further object of the invention is to provide in such support meanspost-like means, a chimney supporting platform mounted rigidly on thepost-like means, and means for attaching the support means within a wallstructure.

A further object of the invention is to provide in such support meansattachment means which is shiftable relative to the post means andincludes a flange for overlying and being attached to a header formingpart of the wall construction.

A further object of the invention is to provide such attachment meanswhich additionally includes depending flanges means, the dependingflange means being positioned alongside the header of the wallconstruction.

A further object of the invention is to provide attachment means for achimney support, which attachment means include a collar slidablyengaged with post means of such support; and

A further object of the invention is to generally improve the design,construction and efliciency of support means as for chimneys.

The means by which the foregoing and other objects of the presentinvention are accomplished and the manner of their accomplishment willbe readily understood from the following specification upon reference tothe accompanying drawings, in which:

Fig. 1 is a perspective view of the preferred form of support means ofthe present invention.

Fig. 2 is a front elevational view, partially fragmentary, illustratingthe support means in position relative to the building construction.

Fig. 3 is a fragmentary side elevational view of the upper end of thepreferred form of support means with parts broken away for purposes ofillustration.

Fig. 4 is a fragmentary side elevational view illustrating a variationin the attachment means of the invention; and

Fig. 5 is a view similar to Fig. 4 of a further variation in theattachment means of the invention.

Referring now to the drawings in which the various parts are indicatedby numerals, the preferred embodiment of the support means comprises anelongated vertically disposed post 11 which is preferably cylindricaland may be a hollow pipe member if desired. To the lower end of post 11a shoe 13 is rigidly fixed, the shoe 13 being provided for seating uponand being attached to a lower level surface of a building constructionsuch as a concrete floor slab 15. To the upper end of post 11 a chimneycarrying platform 17 is rigidly fixed. Platform 17 preferably consistsof a peripheral frame 19 formed of angle iron integrally connected as bywelding, although in some circumstances the frame may be formed byappropriately cutting and bending angle iron material into the desiredshape. Peripheral frame 19 is disposed with one leg of each anglehorizontal and with the other legs of the angles projecting upwardlyfrom the outer edges of the horizontal legs, thus forming a peripheralflanged frame for platform 17. Seated on and integrally secured to thehorizontal flanges of frame 19 is a flat imperforate sheet 21, sheet 21being so connected to frame 19 as to create a water-tight platform.Preferably sheet 21 intermediate its edges is strenghtened by straps 23,and post 11 abuts and is preferably welded to the underside of sheet 21and straps 23 substantially at the midpoint thereof. Preferably theplatform is additionally braced by diagonal struts 25 extending from therespective corners of platform 17 downwardly and inwardly to post 11,struts 25 being rigidly fixed at their upper and outer ends to platform17, and likewise rigidly fixed at their inner and lower ends to post 11.

Intermediate the length of post 11 an attachment means 2 7 is mounted.Preferably attachment means 27 includes a substantially cylindricalhollow collar 29 slidably and rotatably engaged upon post 11 so thatattachment means 37 may be shifted along the length of post 11.Integrally secured to and shiftable with collar 29 is a horizontallydisposed rectangular plate 31 which extends outwardly from the upperextremities of collar 29, and is of a length substantially in excess ofits width. The plate 31 is preferably provided with suitable apertures33 for receiving bolts 35 in order to attach the device in position. Inthe variation illustrated in Fig. 4, attachment means 27 is additionallyprovided with a depending vertically disposed flange 131 which isintegrally connected to and depends from one of the longer edges ofhorizontal plate 31 and is spaced a minor distance from the exterior ofcollar 29, and in the variation shown in Fig. 5 attachment means 27 isprovided with a second vertical flange 231, which similar to verticalflange 131 is integrally connected to and depends from the edge of plate31 opposite to vertical flange 131 and is similarly but oppositelyspaced from collar 29.

In the use of the device it is erected during preliminary stages of thebuilding construction. Thus after the headers 37 and studs 39 have beenerected the headers are =notched out as at 41, notch 41 being of size tofreely, but snugly, receive collar 29. Shoe 13 may be seated on floorslab 15 and secured thereto, preferably the wall framing being cut outas at 43 to accommodate the shoe. Post 11, platform 17 and attachmentmeans 27 are then disposed vertically, and collar 29 is positioned innotch 41. Attachment means 27 maythenbe rotated, if .necessary, untilthe elongated plate 31 is substantially alined with the upper edges ofheaders Z77. Bolts 35 may then be engaged into the headers, thussecuring the attachment means in position, and. the attachment means, asis be lieved plain, retains the support unit in upright position. Theplatform is thus supported above the level of the top of the wall andthe outwardly flanged peripheral frame 19, and sheet 21 are positionedto receive chimney structure 45. The flanged frame 19 serves as anaccurate form for the chimney erection, and being imperforate andwater-tight the platform 17 supports the chimney 45 without danger ofleakage from rain or the like flowing downwardly along the chimney.

It will be seen that in the event the house construction settles orchanges position the attachment of attachment means 27 to theheaderswill not be affected thereby as the sliding engagement between collar 29and post 11 will permit shift of the posts along the collar withoutinterrupting the attachment.

it will be seen that post 11 and collar 29 are of diameters to fitwithin the confines of the wall framing, and when the wall is completedby the application of laths and plaster, or by the application ofcomposite boarding, a flat and uninterrupted surface will be presented.

In the use of the device, varied as shown in Fig. 4,

the vertical flange 131 seats against a vertical face of header 37 andmay be attached thereto by suitable bolts or otherwise as desired, thuscontributing materially to the stability of the attachment. Similarly,in the variation shown in Fig. 5, the flanges 131, 231 will respectivelyembrace the opposite side faces of headers 37, the sliding engagement ofcollar 29 with post 11 permitting the raising of attachment means '27above the level of headers 37 to clear flanges '131, 231, and thatattachment means 27 may then be moved vertically into position withflanges 131, 231 embracing the sides of the headers and attachment plate31 seating on the upper edge of the headers.
